Possibly a similar problem to Hevartid's with C&B116 in 1.18.2.
I am building a huge building including a C&B in a place away from where I usually live.
A fatal freeze occurs when entering the drawing range.
It doesn't seem to happen with C&B115.
It is possible to enter the huge building with 115 and change it to 116, but if you go outside the drawing area again and draw the building again, it will freeze.
I'm using rubidium instead of Optifine, but the same freeze occurred even if I removed it.
